AMAZING IMAGE QUALITY!

GROUND BREAKING!

35% BETTER!

NEVER BEFORE SEEN STOCK IMAGES OF MICROSCOPES!

SCIENTISTS IN PLAID SHIRTS!

NOT A SINGLE PICTURE OF ANYTHING TINY!

DON'T MISS IT!

Article somehow comes up very true m,and yet also a lie.
impossible to see thigns are not pictured in article, so i guess it's true, they are in fact impossible to see, which then makes it a lie that you claim to have seen them but have nothing to show that anyone else can see.

Can you really call it "seeing" when it's not using light?

Sounds like the language has to be refined.

Sounds like some golden tablets of which I've heard tell.

TFA reads like an advertisement for what a break through this invention is without saying why it is better or how it works.

The abstract is slightly better, though the article is paywalled.

Quantum-enhanced nonlinear microscopy

The performance of light microscopes is limited by the stochastic nature of light, which exists in discrete packets of energy known as photons. Randomness in the times that photons are detected introduces shot noise, which fundamentally constrains sensitivity, resolution and speed1. Although the long-established solution to this problem is to increase the intensity of the illumination light, this is not always possible when investigating living systems, because bright lasers can severely disturb biological processes2,3,4. Theory predicts that biological imaging may be improved without increasing light intensity by using quantum photon correlations1,5. Here we experimentally show that quantum correlations allow a signal-to-noise ratio beyond the photodamage limit of conventional microscopy. Our microscope is a coherent Raman microscope that offers subwavelength resolution and incorporates bright quantum correlated illumination. The correlations allow imaging of molecular bonds within a cell with a 35 per cent improved signal-to-noise ratio compared with conventional microscopy, corresponding to a 14 per cent improvement in concentration sensitivity. This enables the observation of biological structures that would not otherwise be resolved. Coherent Raman microscopes allow highly selective biomolecular fingerprinting in unlabelled specimens6,7, but photodamage is a major roadblock for many applications8,9. By showing that the photodamage limit can be overcome, our work will enable order-of-magnitude improvements in the signal-to-noise ratio and the imaging speed.

Here is a figure that escaped the paywall.

Here is an earlier short PDF of the paper where they say the quantum effects depend on using "squeezed light".

"Stochastic Nature of Light".

Fark.com is SO great for discovering potential great band names.
